Be it known that I, FRANK C. `RAwsON,`

a citizen of the "United States, residing at Worcester, in the county of Worcester, State of Massachusetts, have inventedcertain new `and useful Improvements in Stone-Boats, of which the followinglis'a specication, reference `being `had therein tothe accompanying drawing, in which- `Figure l `is apersppctive viewof nay-improved vstone-boat; l ig. 2, a longitudinal `vertical `sectional view thereof; Fig. 3, a transversesectional view on the line 3 3 of Fig. 2 3 Fig. 4, -a vertical longitudinal sectional yview of a .slightly-different form of boat; rand Fig. 5, a transverse vertical secytional Vview thereof, taken on the lline5 5 of Fiv 4.

Stone-boats yas ordinarily constructed have their side edges perpendicular tothe lower Wearingesurfaea thereby forming square G01-'ners along the vertical` longitudinal edges Joflthe wearing-surface. The result of this is `thatwhen the boats are loaded thesecorners makede'ep cuts in all soft lawns or fields over which-they are dragged.

The .main'object of this invention is to` avoid-thesesharp orsquar'e cornersby inclinling va portion of the lower surface of `the fistone-boatialong its longitudinal edges, up wardhandoutward when viewed in transverse verticahsectiom land to -thereby provide 'a i mainbody of the boat, -fwith the` exceptionof `the'inclination of the' sideedges thereof, Aand Lboathavingits bottomslightlyrounded.

fAf-further! object i off the i invention is to pro- 1 wideside strips for the stone-boat, whichare @so constructed `that they'not only form that -portionof lthe `bottom of the'boat which is rounded or inclined .upward and outward,

but which 4also formfside flangesalong the uppersurface of the -stone-boat to retain the #stones thereon, thereby avoiding the neces- :sityof securingextrafside pieces or raves'to the-boat.

Referring to* the'i construction ofboat illus- `tratedrin Figs. l1, 2, and 3 ,A designates the -main-stripsor sectionsiofwhichthe body of' 'the rstone-boat is constructed. These 'strips arefformedin one piece, as shown, and are preferably formed as described inthe patent to M. R. Rawson, No. 802,238,1dated October 17, 1905, and infwhi'ch'the grain of wood runs at an angle to the lowerwearing-surface of the strips and also atan angle to the upwardly and forwardly inclined wearing-surface C thereof, so that. the wear on said inthe grain of the wood rather than parallel with it, as fully set forth in said patent. To the outer edge of the main body of the boat formed of these strips or sections A are secured side pieces a. These side pieces are broader at their under side orwearing-surface than on top,the side edges of said piecesbeing substantially radial, so that the side pieces taperupwardly when viewed in crosssection, as `shown clearly in Fig. 3. The side edges of the main body of the boat are perpendicular to the upper'surface thereof. The inner edgeof each of said side strips a is secured squarely against one vertical edgeof the body of the boat, with the result that the bottom and top of each of said side stripsinclines upwardly and outwardly, as shown in Fig. 3. By thus constructing the side pieces a the bottom or wearing-surface of the boat is inclined upwardly along the longitudinal edges thereof, and the topoftheboat is also similarly inclined upwardly along said edges. To connect all of the sections of the'stoneboat together, transverse end vpieces Bare faces of the side pieces a, as shown clearlyin Figs. l and 3. The side piecesa are preferably ofthe same shape as the sectionsofthe these side pieces are preferablyucut from va plank in' such a manner that the grainiofthe `wood will runat an angle tothe lower Awearing-surface of the body of the stripfandalso wat an angle to the under wearing-surface of thenose or forward part of the strip Ain the same manner as the grain ofthe section'Afo'f the main body of'theboat. Itwillsbeseen i that by forming these yside pieces asdescribed the under surfaces thereof round'off'the bot `tom of the boat and effectually preventthe lowerl longitudinal edges thereof from cutting vsoft lawns or iieldswhen the boat is loaded, `and Vthe upper surface of said side pieces form longitudinal raised .flanges or raves, which serve to retain thel stones'on thefboat,

thus doing away with the necessity iofrse'euring extra pieces to the boat for this purpose. It will further be noted that these results are secured without weakening the boat in the least and that the side flanges or raves along clined surface is to a certain extentagainst l the upper longitudinal edges of the boat are IOO IIO

as permanent as the boat itself. These raves as ordinarily provided are soon broken and worn and must be frequently renewed.

In Figs. 4 and 5 a slightly-different form of boat is shown. As shown in these figures, the boat is constructed of the strips A', which form the main body part of the boat, and the nose-pieces d, which are secured to the forward ends of the strips A. These nosepieces are cut out at their rear ends, as at d, to receive the forward ends of the strips A, and a transverse connecting-strip E is secured over the overlapping parts of these strips by bolts or other suitable fastening means, as shown in Fig. 4. The ends of the strips A and the noseepieces D are connected together by transverse end pieces B. Along the longitudinal edges of the main body of the boat are secured the side pieces a', which are substantially similar in transverse shape to the strips a, (shown in Fig. 3,) so that the boat along its longitudinal edges will incline upwardly and outwardly, as described with respect to Figs. 1, 2, and 3. At the side edges of the nose portion of the boat, as illustrated in Figs. 4 and 5, are secured the side piecesd, which are of the same shape longitudinally as the nose-pieces D and of the same shape transversely as the side pieces A, so that the nose portion of the boat along its longitudinal edge will incline upwardly and outwardly and correspond in transverse section to the transverse section of the main body of the boat.

An aperture@2 is formed in the forward end of the boat, (illustrated in Figs. 1 and 2,)

4and a similar aperture cl2 is formed in the forward end of the boat (illustrated in Fig. 4) in order that a draft-chain or other device may Abe attached thereto.

ters Patent, is-

1. A stone-boat comprising a main body part formed with a series of strips cut from a single piece of wood and havingthe grain thereof running at an angle to the .under wearing-surface thereof and having their upper and lower surfaces substantially fiat in transverse section, and side strips cut from a single piece of wood and having the grain thereof running at an angle to the under formed with the upwardly and forwardly y extending wearing-surfaceV C on the under side thereof at an angle to the under side -of the main portion of said strip, the grain of the wood running at an angle to said wearing portions of said strips, the upper and lower surfaces of said body part being substantially flat in transverse section, and side strips cut from a single piece of wood and of the same shape in longitudinal section as the strips of the main part of the boat and being upwardly tapered in transverse section, whereby the upper and lower surfaces thereof will incline upwardly and outwardly with respect to the corresponding surfaces of the main body part, substantially as described and for the purpose set forth.

3. A stone-boat comprising a main body part formed of a series of wood strips whose upper and lower surfaces are substantially horizontal and whose side edges are perpendicular to said upper and lower surfaces, and with a forward upward extending portion,`

the under side of the said forward portion of the boat being inclined upwardly and forwardly and at an angle to the grain of the wood, whereby the wear on said forward part will be on the ends of the wood fibers instead of along the edges thereof, and side strips upwardly tapered in transverse section throughout their length, whereby when they are connected to the perpendicular sides of the body part of theboat the upper and lower surfaces of said side strips will incline upwardly and outwardly, the under side of the forward part of said side strips being inclined upwardly and forwardly, whereby the wear thereon will be against the ends of the fiber of said side strips, and the said side strips will form side flanges for the boat throughout the length thereof.

In testimony whereof I hereunto aflix my signature, in the presence of two witnesses, this 21st day of July, 1906.
